Bird Box is a 2018 American post-apocalyptic horror thriller film directed by Susanne Bier and written by Eric Heisserer, based on the 2014 novel by Josh Malerman. The film follows the character Malorie Hayes, played by Sandra Bullock, as she tries to protect herself and two children from entities which cause people who look at them to kill themselves.
In a post-apocalyptic world, Malorie Hayes informs two young children that they will go down a river in a rowboat. She sternly instructs them not to remove their blindfolds, or they will die.
Five years earlier, a pregnant Malorie is visited by her sister, Jessica. A news broadcast reports unexplained mass suicides spreading across Europe and Asia. After a prenatal checkup, Malorie witnesses a woman smashing her head repeatedly into the hospital window. Others start acting suicidal as well, causing panic and chaos. Afterward, Malorie hurries to leave the scene with Jessica. While steering away from the hospital, Jessica sees something inexplicable that drives her insane and she deliberately crashes her car. She then walks in front of a speeding truck and is killed.
